Application filed April 24, 1,909. Serial No. 491,980.

To all w/iom it may concern:

Be it known that I, RICHARD lV. Hamann, a citizen of the Unitedv States, and resident vof St. Louis, Missouri, have invented certain l nenr and useful Improvements Iin Boiler- Tube-Cleaner Nozzles, of which the follow-- ing'is a specification containing a full, clear.

and exact description, reference being had to the accompanying' drawings, forming a. part hereof.

This invention relates to boiler tube cleaners, and has for its object the provision of a nozzle which will eliminate the, annoyance and danger incident to `moisture collecting in devices of this class.

A further object of my invention is to, provide a sectional nozzle which will make device to either a single boiler or to a bati tery of boilers. To the above purposes, my invention consists in certain novel features of'construction and arrangement of parts which will be hereinafter more fully described, pointed out in the claims and illustrated in the accompanying drawings, in which: l' liigure 1 shows'my improved nozzle .in position in a boiler; Fig. .2 is a. longitudinal sectional elevationV ot' the nozzle; Fig. l is atransverse sectional elevation on the line sectional elevation showing a modified form of nozzle..

Referring by numerals to the accompany ing drawings: 1 and 2 designate thev side walls of a slngle boiler setting. 3 indicates a series of tubes positioned therein.

4 indicates a series of heat insulating blocks supported from the tubes 3 bythe hangers 5. Supported within and partially zle 6. Inserted between the walls ot4 tbe nozzle 6 is a perforated tube.

The nozzle 6 comprises a sect-ion 8 having a tapered flange 9, a shoulder 10 and an annularly beveled end 11. A section 12 f comprising an annular flange extension 13 at its one end, and a face 14 corresponding i to the faces 11 of section 8. A section 15 havin at itsone end afiange 16 identical with t e :Flange 13 in section 1.2, and an ani nular flange` 17 and shoulder 18. Pins 19 are arranged to be placed within openings formed in the .flanges 9, 11, 153, 111-, 1G- and i .17 to hold the sections against separatioinl and close the a sectional nozi A cap l2O is placed over the flange 9 of the .section S, and secured thereto by' one of the pins 19. Anipple 9,1 is arranged within the bevel face 1T ot' section 15 and is internally threaded and held Within the section 15 by one ot the pins 19. Each of the sections 8, l2 and l5 is provided with a series of apertures A. tube 23 is positioned Within the sections 8, 12 and l5 and held and embraced at its one end by the shoulder 10 of section S, and at its other end by the shoulder 18 oi' sectionl5, the tube 23 being provided at its one end with a flange collar 94, which [lange collar 1s designe( to revent movement of the tube 23 longitudinally relative to the sections 8, 12 and 15. A series Vof apertures 25 1s iorlned 1n thetube Q3 out of alinement with the apertures 2Q. A section ot tubing 26 R21-and alever is fixed thereto.

is threaded withinthe nipple A coupling is fixed to the free end of the tube Q6 and is loosely' fixed to a. steam supply pipe 29. The Wall 2 of the boiler settin 1s provided with an annular sleeve 30, an a rapill is arranged to embrace the tube 26 opening formed by the sleeve 30. r

The nozzle shown in Fig.,4 comprises a series of sections 32, interlocking-1n a manner similar to the form shown in Fig. 3 3 3 of Fig. 1; and Fig. 4 is a longitudinal n v s e n each of which sections 1s provided with an boiler setting and designed to dislodge andV remove soot, ashes and other' sediment from boiler tubes, it being understood furthen, that the heat insulating blocks are necessary to protect the nozzle against the heat With-in the boiler. ,i 4

The lever ,QT is arranged for a rotary nmvenicnt of' the tubes, which provide a.' means tor covering a greater area 4within the, boiler by the steam issuing At'rom the apertures 22.

It will be obvious that moisture contained within t-he steam supply pipe 29, connecting pipe 2G and the tube 23, will, when live, dry steam `is applied, be driven into the space be nuten.

aaA

tween the sections 8, 12, and l5 and the tube Q3, whereby the action of the heat from the furnace will evaporate or convert such moisture into steam and discharge nothing but live, dry steam through the apertures 22 in the boiler.

I claim:

l. A nozzle for boiler tube cleaners, comprising an inner and outer casing spaced apart so as to form a chamber between them, both of said casings being provided with a series of openings throughout their length and Ineansto prevent movement of the casings relative to each other.

2. A nozzle for boiler tube cleaners, comprising an inner and outer casing spaced apart so as to form a chamber .between the inner wall of the outer casing and the outer wall of the inner casing, both of said casings being provided witha series of openings f throughout their length and means to pretheir length.

' prisinor .vent movement of the casings relative to each other.

3. A nozzle for boiler tube cleaners, comprising a sectional outer casing and a sectional inner easing, said casings being `spaced apart so as to form a chamber between them, means for locking the sections against movement relativelto each other and apertures formed in each of the sections throughout It. A nozzle of the class described, coinprisinv` an outer casing provided with 'a series o? openings, an inner casing rovided with a series of openings dispose in said outer easing, there being a continuous cham ber between the exterior surface of'said inner casing and the inner surface of the'outer casing and meansv to prevent movement of the easings relative to each other.

5. A nozzle of the class described, coman outercasing provided with a series o? with a series of openings ofless size than the openings formed in the outer casing, disposed in said outer casing, there being a continuous chamber between the exterior surface of said inner casing and the inner surface of the outer casing and means to prevent rotary movement ot the easngs relative to each other.

6. A nozzle for boiler' tube cleaners, coni.-

.prising an outer tube having a series of apertures formed therein in longitudinal alinement, a tube within the outer :tube hav'- ing' a plurality of openings formed therein,

openings, an inner casing provided none of which openings aline with the apertures in the outer tubing, means for closing the one end lof the outer tubing, means for connecting a steam supply pipe with the opposite end of the inner tubing means for locking the tubes against movement relative to each other and means for rocking the tubes.

7. A nozzle for boiler tube cleaners, comprising an outer tubing composed of sections, means for locking said sections together, a series of apertures formed therein in longitudinal alinement, a. tube Within the outer tube having a plurality of openings formed therein, none of which openings aline with the apertures in thn outer tubing, means for closing the. one end of the outer tubing means'for connecting a steam supply pipe with the opposite end otthe inner tubing means for locking the tubes against rotary' movement relative to each other and means for rocking the tubes in unison.

8. In a nozzle for boiler tube cleaners, an outer tube composed of sections, tapering joints at each end portion ofeach section and pins Jfor locking said sections together, a series of apertures formed therein in longitudinal alinement, a tube within the outer tube having a plurality of openings formed therein, none of which openlngs aline with the apertures in the outer tubing, means for closing the one end of the outer tubing and means for connecting a steam supply pipe `with the opposite end of the inner tubing.

9. ln a nozzle for boiler tube cleaners, an outerl tube composed of sections having pins for locking the sections together, a cap for closing the oneend of the nozzle, a means for connecting a steam supply pipe with the other end of the nozzle, apertures formed in the various sections in longitudinal alineinent, a tube placed Within each section of the outer tube, a plurality of apertures formed therein, none of which will aline with the apertures in the outer tubino, heat insulating blocks arranged to partially e1nbrace the nozzle, means for supporting the blocks within the boiler setting and means for rotating the nozzle within the heat insulating blocks.

ln testimony wheroft, l have signed my name to this specification, inpresence of two subscribing witnesses.
